An interior permanent magnet motor includes a stator comprising a hollow and a plurality of coils provided around the hollow; and a rotor rotatably disposed in the hollow of the stator and comprising a plurality of permanent magnets therein. Each of the plurality of permanent magnets of the rotor comprises a central permanent magnet; a pair of side permanent magnets provided at opposite ends of the central permanent magnet to be inclined toward an outer circumferential surface of the rotor; and a pair of bathers provided between the central permanent magnet and the pair of side permanent magnets, a thickness of each of the pair of bathers is equal to or greater than a thickness of the central permanent magnet. The thickness of the central permanent magnet is greater than a thickness of each of the pair of side permanent magnets.
